Timesulin is an electronic device and can withstand ambient environmental moisture like that inside a fridge, or if you happen to have it on a shelf in the bathroom while taking a shower.

We don't recommend using a Timesulin cap inside an evaporative cooling unit without a waterproof cover to protect your smart cap. Don't submerge your Timesulin cap under water either.

The best recommendation is to treat Timesulin like all other electronic devices.
